Fillers for Acne Scars: What Is It, How It Works, 3 Types, Benefits, and Cost

Acne scars are a common skin concern that affects many individuals, leaving behind visible marks long after the acne has cleared. These scars can range from shallow depressions to deep pits, often impacting one’s confidence and self-esteem. Understanding how acne scars form is the first step towards choosing an appropriate treatment.

With advancements in aesthetic treatments, fillers have emerged as an option for addressing these scars. In this guide, we’ll explore the world of fillers for acne scars, detailing their types, benefits, and costs, providing you with the information needed to make an informed decision.

What Are Fillers for Acne Scars?

Fillers are injectable substances that enhance the skin’s appearance by filling depressions and restoring volume. Commonly made from hyaluronic acid, calcium hydroxyapatite, poly-L-lactic acid, or polymethylmethacrylate microspheres, these fillers rejuvenate the face by reducing signs of ageing and improving skin texture. Hyaluronic acid is particularly favoured due to its natural occurrence in the body and ability to retain moisture, creating a plumping effect that smooths the skin.

When applied to acne scars such as atrophic scars, boxcar scars, rolling scars and other severe acne scars, fillers smooth out uneven skin textures, resulting in a more even complexion. The process involves injecting the filler beneath the scarred area, lifting the depression, and creating a smoother surface. These minimally invasive treatments offer immediate results, making them attractive for those seeking quick improvements.

In Dr Justin Boey’s experience, fillers improve skin smoothness and boost patients’ confidence by reducing the visibility of scars and enhancing facial contours. His approach focuses on careful filler selection tailored to individual facial structures and desired outcomes, ensuring personalised treatments that achieve natural-looking results.

Types of Fillers Used for Acne Scars

Several types of fillers are available, each with unique properties and benefits. Understanding these differences can help determine the most suitable option for your needs.

Hyaluronic Acid Fillers

Hyaluronic acid fillers are among the most commonly used for acne scarring. This substance naturally occurs in the body and maintains skin hydration and elasticity. When injected, hyaluronic acid fillers attract moisture, adding volume to the scarred area and improving skin texture.

These fillers are temporary, typically lasting six to twelve months, but they offer the advantage of being reversible if desired. They’re ideal for treating shallow to moderate scars and provide a natural-looking enhancement.

Collagen-Based Fillers

Collagen-based fillers were among the first to be used in aesthetic treatments. Collagen is a protein that provides structure and support to the skin. Injecting collagen-based fillers into acne scars can help restore volume and smoothness, particularly in older scars with diminished collagen production.

While effective, these fillers are less commonly used today due to the development of newer materials. However, they remain a valuable option for certain individuals, offering results typically lasting three to six months.

Semi-Permanent Fillers

Semi-permanent fillers offer longer-lasting results compared to their temporary counterparts. These fillers contain substances that stimulate collagen production in the skin, providing ongoing improvement even after the filler has been absorbed.

Poly-L-lactic acid is a common material used in semi-permanent fillers. It works gradually, requiring multiple sessions to achieve the desired outcome. The effects can last up to two years, making it a cost-effective option for those seeking extended results.

How Fillers Work to Treat Acne Scars

Fillers address acne scars by adding volume to depressed areas, effectively raising them to the level of the surrounding skin. The process involves injecting dermal filler material beneath the skin’s surface, acting as a support structure. This smooths out the scar’s appearance, reduces visibility, and creates a more uniform texture, with results typically visible immediately.

Fillers like hyaluronic acid and calcium hydroxyapatite are injectable substances that also treat deep wrinkles, add volume, and enhance facial contours. They integrate with the skin’s natural structure, providing an immediate plump and smooth appearance. Hyaluronic acid fillers bind with water molecules for a hydrated, volumised effect that supports collagen production, improving skin elasticity and firmness. Calcium hydroxyapatite fillers offer a scaffold for natural collagen production, adding volume and contributing to a youthful look.

The effects of dermal filler treatment are usually temporary, lasting from several months to a couple of years, depending on the type of filler and individual lifestyle factors. Regular treatments are often recommended to ensure sustained results, with sessions tailored to meet evolving aesthetic needs.

Benefits of Using Fillers for Acne Scars

Fillers offer several advantages as a treatment option for acne scars:

• Immediate results – One of the most appealing aspects of fillers is their ability to provide instant improvement in skin appearance.
• Minimal downtime – Unlike more invasive procedures, fillers require minimal recovery time, allowing individuals to resume their daily activities almost immediately.
• Customisable treatments – Fillers can be tailored to suit individual needs, addressing various scar types and providing personalised enhancement.

What to Expect During the Procedure?

The filler procedure is relatively straightforward and typically completed within a short time frame. Before the treatment, a consultation with Dr. Boey, an experienced aesthetic practitioner, is essential to discuss your goals and assess the suitability of the filler type. Dr Boey will cleanse the treatment area and may apply a numbing cream to minimise discomfort.

The filler is then injected into the targeted scars using a fine needle. The number of injections will depend on the extent and severity of the scarring. After the procedure, some redness and swelling may occur but usually subside within a few days.

Proper aftercare, including avoiding excessive sun exposure and following specific instructions from Dr Boey, is crucial to ensure optimal results.

Safety, Side Effects, and Risks

Fillers are generally considered safe when administered by a qualified practitioner. However, as with any medical procedure, there are potential risks and side effects. Common side effects after dermal fillers include temporary redness, swelling, and bruising at the injection site. These are typically mild and resolve on their own within a few days.

More severe side effects such as infection, allergic reactions, or lumps may occur in rare cases. Choosing a reputable and experienced practitioner is essential to minimise these risks and ensure a safe treatment experience.

How Long Do Results Last?

The duration of filler results can vary depending on the type of filler used and individual factors. Hyaluronic acid fillers typically last six to twelve months, while collagen-based fillers may last three to six months. Semi-permanent fillers can provide results lasting up to two years.

Factors Affecting Longevity

Several factors can influence how long the results of fillers will last:

• Skin type – Individual skin characteristics can affect how quickly the body metabolises the filler material. –  
• Filler type – Different fillers have varying longevity, with semi-permanent options generally lasting longer than temporary ones.
• Lifestyle – Factors such as smoking, sun exposure, and skin care habits can impact the durability of filler results.

Cost of Fillers for Acne Scar Treatment

When considering fillers for acne scar treatment in Singapore, it’s important to know the typical price range, which generally falls between $600 to $1,000 per syringe. This cost can vary based on factors such as the type of filler used, the practitioner’s expertise, and the specific clinic offering the service. Despite the investment, many find that the enhanced skin appearance and confidence gained from these treatments make them worthwhile.

What Influences the Cost?

Several factors can affect the overall cost of filler treatments:

• Location – Prices may vary based on the geographical location of the clinic, with urban areas often having higher fees.
• Practitioner expertise – Experienced practitioners may charge more for their services due to their skill and reputation.
• Type of filler – Different fillers come with varying price points, with semi-permanent options generally being more expensive.

Comparison with Other Acne Scar Treatments

Fillers are just one of several options available for treating acne scars. Other common treatments include microneedling and laser therapy. Fillers provide immediate results with minimal downtime, making them an attractive option for those seeking quick improvement. Microneedling involves using fine needles to create controlled micro-injuries in the skin, stimulating collagen production and improving scar texture over time. Laser therapy uses focused light to resurface the skin and reduce scar appearance.

Conclusion

Fillers for acne scars can enhance skin texture and address specific concerns caused by scarring. With immediate results and minimal recovery time, they are a practical treatment for those seeking non-surgical solutions. However, the effectiveness of fillers depends on factors such as the type of scars, your skin condition, and your treatment goals.

Dr Boey emphasises the importance of consulting with a qualified professional to determine the most suitable filler type and personalised treatment plan. Understanding your individual goals and expectations can help guide the decision-making process.

Whether you choose fillers or other treatment options, the focus should be finding a solution that aligns with your desired outcomes and supports your confidence.
